acetal plastic

Acetal is a crystalline thermoplastic polymer with a high melting point.It offers a high modulus of elasticity combined with great strength, stiffness and resistance to abrasion. Moisture has little to no effect on acetal resin, and because of this, the dimensional stability of close tolerance fabricated items is excellent. It is suitable for mechanical parts or electrical insulators that require structural strength at above normal temperatures.

 

PROPERTIES High modules of elasticity. High strength and stiffness. Low coefficient of friction. Easily fabricated with hand tools and automatic production machinery. Good abrasion and impact resistance. Low moisture absorption. Excellent machinability Natural lubricity. Resistant to gaxsoline, solvents, and other neutral chemicals. Useful in air temperatures of -60° to +320°.
GRADES Delrin 100® series: High viscosity grade of resin for production of rod, slab and tubing to be machined. 
Delrin 500® series: General purpose resin used in production of rod and slab. 
Delrin 570® series: Resin containing glass fibers. Used where high stiffness, creep resistance and better dimensional stability are required. 
Delrin AF®: Resin containing TEFLON® fibers. Used where low coefficient of friction, high resistance to abrasion and wear are required.
APPLICATIONS

Delrin's overall combination of physical, tribological and environmental properties make it ideal for many industrial wear and mechanical applications. Pump and valve components, gears, bearings, bushings, rollers, fittings and electrical insulator parts.
